You do really need a piece of B&O with the Speaker link connection - however it sounds to me that you have been sold a pup - I would attempt to return these.There are lots of Pentas out there - these days, I would strongly suggest sticking to the Penta 3. You can still, last time I looked, get new midrange units.

Someone told me B&O charge an extortionate amount until you trade your old mids in, so if true it sounds like they are running out of stock!

But I agree if you can send these back, especially with the shipping damage on top!

I recently heard the same. A unit costs €60,- and you have to return the old ones. Looks like they refoam them themselves.

I should be honest - I bought my other Pentas at extremely good prices and didn't do too badly on these. Whilst the seller didn't take them back, he was good enough to offer a partial refund. So I have two 'good' pairs (1x Penta 2, 1x Penta 3) requiring slight refurbushing and one 'not so good' pair (1x Penta 1) for whom I've got to decide quickly whether I repair and keep them, do something wild with them and keep them or part them out and cut losses. My partner, well, she likes the sound of the pair that's currently connected but would like me to do something constructive with the other four in short order...

I don't like the displays on them and am keen to work out if they work or otherwise to gauge whether they can be sold or not. I'll likely remanufacture an opaque black (or very dark grey) lens cover. The 2's appear to have had the displays upgraded to some sort of two-line LCD and I'm honestly just keen to see what happens when it's turned on.

So we're currently at 'sell the 1's and possibly the other displays' with the 1's either in parts or as complete units. If selling as complete units I'd not feel comfortable passing them on with the midrange units in that condition. I'll post a pic later... If they can be 're refoamed' I'll order rings.

OK! Four Penta's worth of midrange drivers (that's 16 of them!) removed, old foams out of my Penta 2's and 'new, professionally refoamed' kit off my Penta 1's... what a disaster! I had thought some of the horror stories on refoaming on this forum to be a bit extreme, but no - completely possible!

What a sad way to treat a lovely pair of speakers... one of the speakers was completed with way too much glue, the other with clearly not enough. It'd seem no pressure was used when curing the glue either - a very 'lumpy' finish. PVA (woodworker's glue) was used and let me assure anyone considering using this on their speakers and thinking about keeping them well into the next refoam... don't! It's absolutely awful to get off on a paper cone! There appears to be no way of doing this without some degree of cone damage. Just use cement!

Two of the drivers will simply need to be replaced - 1 having been used when the cone clearly wasn't centered, the other from simply too much glueleading no way to get rid of it without taking out an amount of the cone. Most suffered some light surface tearing and are now cosmetically fine (after very light sanding) though T/S parameters are likey to have changed... not good. The one that needs to go still looks 'normal' but it'd rather it play 'normal' too.

I'll post some pics after cleaning up the baskets and vacuuming everything clean.

Those having refoamed their own - did you shim? I'm headed that way... 

Of (trivial) interest it'd seem B&O went from philips screws on the Penta 1 to Torx screws on the 2/3's...

No I did not and never will at leat not for these type of drivers. I will consider using the batterie method for the next refoaming job, but cutting out the dustcaps, no way.

Looks yours has been done by a boatworker with two left feet!😁

Just finished another 8 and will connect them later this week! Will let you hear about the results....

@ Leslie,

Did you use rubber instead of foamrings?

It's a know fact that rubber lasts longer, but sounds different.

Foam.  Have been using rubber before but it's quite difficult to handle!

Have been talking with Martin about this refoaming/shimming thing and my or better our conclusion is, if you don't have the skills or you have two left hands or feet let a pro do the job!

Time is a important factor, take your time with refoaming. But that's something you already know 😕

I've done a set of CX's 2 weeks ago. And the result was positive despite that I'm not a real supporter of refoaming.

The tolerance is close to zero when it comes to the cone.
